最佳答案
Could not locate PropertySource: I/O error on GET request for "http://localhost:8761/config/diviso/dev/master": Connection refused: connect; nested exception is java.net.ConnectException: Connection refused
此警告消息意味着您的应用程序无法连接到其 Spring Cloud 配置服务器:JHipster Registry。
在 dev 配置文件中，这只是一个警告，您可以忽略它，因为您的应用程序可以使用 sc/main/resources/config 中的本地应用程序属性运行.
在prod配置文件中，这将是一个错误，并且您的应用程序将无法启动。注册表必须在您的应用程序之前启动，因为这是您的应用程序获取其应用程序属性并将其自身注册为 Eureka 客户端的地方。
因此，在开发中，您可以忽略此警告，或者如果它让您烦恼，您可以启动注册表。
如果您的应用程序是整体应用程序而不是微服务应用程序，您可以选择排除发现客户端问题，如果不需要水平扩展，部署会更简单。
